Influenza vaccination during pregnancy and influencing factors in Korea: A multicenter questionnaire study of pregnant women and obstetrics and gynecology doctors.

Background: Although the World Health Organization and health authorities in most countries recommend that pregnant women receive inactivated influenza virus vaccines, coverage remains low. This study aimed to investigate (1) the proportion of pregnant women who received an influenza vaccination and influencing factors and (2) the proportion of obstetrics and gynecology (OBGYN) doctors who routinely recommend influenza vaccination to pregnant women and influencing factors.

Methods: Two separate, anonymized questionnaires were developed for physicians and pregnant and postpartum women and were distributed to multicenters and clinics in South Korea.

Synthesis of Either C2- or C4'-Alkylated Derivatives of Honokiol and Their Biological Evaluation for Anti-inflammatory Activity.

Honokiol, a biphenolic neolignan isolated from Magnolia officinalis, was reported to have a promising anti-inflammatory activity for the treatment of various diseases. There are many efforts on the synthesis and structure-activity relationship of honokiol derivatives. However, regioselective O-alkylation of honokiol remains a challenge and serves as a tool to provide not only some derivatives but also chemical probes for target identification and mode of action.

Umbilical reconstruction using a modified inverted C-V flap with conjoint flaps.

The umbilicus is an important aesthetic feature of the abdomen. Because of its location, the umbilicus can be injured after abdominal surgical procedures. Various methods have been devised to reconstruct the umbilicus by using local flaps, purse-string sutures, or a cartilage graft, but there are no ideal methods.

Pentagonal hinge osteotomy for reduction of the wide nasal base of Asians.

We designed a pentagonal hinge osteotomy procedure for reduction of the wide nasal base of Asians. Minimal dissection was performed on the nasal bone and frontal process of the maxilla. Following determination of the desired width of the nose, partial-thickness osteotomy was performed first, using a hand saw at the midlevel from the midline to the lateral osteotomy line.

An anatomical study of the saphenous nerve, artery, and artery perforators within the thigh using cadaveric dissection.

Although the saphenous flap has been used in reconstruction as a free flap, there has not yet been an anatomic study about the perforators of the saphenous artery. The aim of this study is to investigate the anatomy of the saphenous artery and the number and locations of its perforators. We dissected parts of 10 legs from 5 cadavers.
